ABSTRACT The present invention relates to an interface for an electronic blackboard and more particularly to a method and apparatus for determining the X-Y coordinates of a point on a writing surface and the output of the point on a video display device on a real-time basis. The electronic blackboard display system has both a contact mode and a self-calibration mode. The self-calibration mode is functional during times of non-contact. Contact signals from the electronic blackboard are digitized and displayed on a video display terminal in a colour corresponding to a pen tray signal. The microprocessor can also output signals through a modem to a remote video display terminal.
